Eglise Saint Laurent

Oger church is dedicated to Saint-Laurent, patron saint of the commune, and dates from the second half of the 12th century. The bell tower is Romanesque, while the choir is primitive Gothic. Inside, 48 17th-century stalls from the former Toussaints Abbey in Châlons-en-Champagne and 30 late 19th-century stained-glass windows have been preserved.
Saint-Laurent Church has been recognized as a "welcoming church".
